[users@httpd] How to know the status of backend server(worker) running in loadbalancing environment (With mod_proxy_loadbalancer)
Hi experts,
I setup my environment like this :
----------------
tomcat1
Client ------ apache ------
----------------
tomcat2
Here I setup backend servers in loadbalancing environment using with
mod_proxy_loadbalancer.
I want to know that which tomcat server is holding how much load currently?
(related to all about worker status)
Is there any utility or tool available to know about it in apache.
I am using Apache2.2.8 mod_proxy2.2.8 with tomcat5.5.
If any body can help me , suggestions are welcome.
Narendra

Hi,
Thanks a lot for reply.
Ya this is very important info that make sense.
Here elected is one of the attribute that shows how many time worker has
elected. Is there any more attribute related to it that can give the info
that how many request or how many session are currently holed by any worker.
Thanks
Narendra

Configure balancer-manager as I showed in my previous letter. Then use
you browser to go to http://localhost/balancer-manager. You'll see a
web page with a list of configured balancer members and information on
how many time each member was elected and how much traffic was passed
to each member. Something like that:
LoadBalancer Status for balancer://test-lb
StickySession Timeout FailoverAttempts Method
0 1 byrequests
Worker URL Route RouteRedir Factor Set Status Elected To
From
http://member-1 1 0 Ok 951 616K 558K
http://member-2 1 0 Ok 951 660K 622K

Hi Serge Dubrouski
First of all thanks a lot for giving idea about it.
Can you please tell me more about that how load balancer-manager shows that
how many times this or that balancer member was elected and how many request
any worker is currently serving.
Narendra

That depends on you definition of "load". load-balancer shows you how
many times this or that balancer member was elected, that gives you a
number of requests processed by each member. If you need to know CPU
load, or traffic load then you need to use other tools, perhaps SNMP
monitors.

That depends on you definition of "load". load-balancer shows you how
many times this or that balancer member was elected, that gives you a

Thanks for replying,
I configured it earlier 'balancer-manager'
But it does not give complete info related what I want exactly.
Means I want currently which server (worker) has how much load?
Any suggestions are welcome.

Actually that depends on how you configured your LoadBalancer, see
loadfactor parameter.

Apache has balancer-manager handler that can give you some limited
information about balancer memebers. You can configure it like that:
<Location /balancer-manager>
SetHandler balancer-manager
Order allow,deny
Allow from 127.0.0.1
</Location>
